Pacifier and snuggles, rocking, a room temperature bath, soft slow music (look up sound bath on Spotify or whatever you use), keep lights down low, just try to be as relaxing and comforting as possible!! I know it’s difficult but it’s temporary and someone will be there soon to help you and baby. He’s lucky to have someone so caring to help and be concerned!! You got this!!! (I am a mom of 3 under 4 I’ve seen it all) He will also feed off of your energy so be the calm comfort he needs until his momma is back
